To all whom it may concern:

llc it known that l, Fnincis N. H. CLAY? a citizen of the United States, residing at l ittsburg, in the State of Pennsylvania, have invented certain row and useful linproveinents in Bottle-Closures, of which the following. is a specification.

My invention relates to metallic closing devices for bottles, jars and the like; its principal objects are. to avoid the necessity of resilient packing, to more easily apply. and secure suchclosures, to make a closing cap that may be used over and over, and to generally improve the efiiciency of bottle. closures.

More. specifically, the object is also to provith leverage devices by which an elastic prcssuie. may be induced on the cOVcl of the bottle. anthto enable the closure to readily adjust itself to irregularities in the form of the bottle head. I

These objects and other advantages to appear hereinafter, I attain by the structure and ope 'ation shoivnin several forms in lhe accompanying drawings forming part of this specification, and wherein-- Figure l is a. central vertical section through an ordinary bottle head and one form of the closing cap placed thereon but not yet secured in place, and Fig. 9 is the sonic section. with the closure secured. Fig. 2) is a lop plan of the cap in the condition of Fig. 1. Fig. 4: shows a form of blank, and l 5 is a side elevation of the cap made hcrel'roni. Fig. 6 shows an alternative form tor otherwise making the rcsilient vcrlicztl pressure. I

instead oi. relying upon the resiliency of a packing, such as cork or rubber, the stopper here shown is held down resiliently by distortion of the metal of which the cap is made, being a self-induced elastic pressure. The packing is only used to cover unevenness in the bottle and cap and need not be resilient. lvlorcovcr the elastic pressure maintained by the cap upon the packing is origi nally induced by av leverage device attached to the covering plate and engaging theanchoragc ledge of the bottle to strain the holding members out of original position. Thus in the form shown it will be seen that the bottle head 14: has an anchorage ledge 15 and the cap comprises a coverltl having deending spring legs 31 connected together at bottoms by a corrugated ring 32. Originally the cap is in the form shown in Fi s. 1, 3 and 5 and it. is laced on the bottle with a. packing disk pro crably parailined paper, 33. The inwardly bent edges of the ring 32 snap under the ledge 15 whereupon a tool is applied which will push. downward and inward the outer edges of ring 32, placin it in the position shown in Fig. 2. This overage action of the ring 32 draws down the cap stretching arms 31 and compressing the. packing over the mouth of the bottle.

it will be evidentthat in the operation of placing the stopper the ring 32 can conform itself to any irregularity in sizo or shape of the head or ledge; and also that the cover is held down resiliently at various places around its periphery, so that the top of the bottle does not. require to be even. The stop per in fact can conform to any size or shape of head and can be used on any bottle which has a ledge to engage the ring 82. The stopper is opened by prying loose the ring 32 with any convenient tool such as a key or ice pick or knife edge, orlihe ordinary open ing tools found on *v'hje niarkct can he used.

It is to be noted that all the space outside the packing disk is open for quick drying of the liquid which will. prevent rust and make a very sanitary stopper.

In Fig. 6 is shown a modification inwhich the covering disk 16 has a downward in dented rib 3 which may engage the packing disk on a shar point. The downward flange 35 is continuous in this instance to near the bottom of the corrugations 36 therein and hhe separate legs 19 are turned upward to as lQX GIS engaging by their ends on the ledge of the hottleheud. These arms may have corrugations 87 for additional resiliency. This stopper is applied by pressing down the corrugations 36, which will compress them and force the lower ends of the arms 19 inward so as to draw down the cover 16 and hold it under resilieni pressure. The advantages of the. device will be readily apparent to those familiar with the a rt.

Having thus described my invention and. illustrated its use, what I claini'and dcsirc'to secure by Letters Patent, is the following:

1. A bottle closure comprising a cover, at.- tached arms embracing the bottle head, members integralwith the. arms and singularly disposed in position to engage under the ledge of the bottle head,- parts of said onill Q I asaaaa gaging members being arches of metal adapted to retain the engagement by bending the arches, substantially as described.

2. The combination with a bottle having an outside annular ledge, of a closure comprising a cover, members embracing the head, and an integral part of said embracing members standing at an inclination and adapted to engage thevledge on the edge of the metal, said engaging parts being composed of arches of metahwhereby bending said arches may retain the engaging members permanently in engaging position, substantially as described.

3. In a bottle closure the combination of a cover for the bottle mouth, means to engage the bottle head, and an elastic connecting part between the cover and engaging means, adapted to be stretched bythe latter as it is moved to its final position.

4. 'In a bottle closure the combination of a cover having elastic legs and means on the legs to simultaneously engage the head of the bottle and to place the said legs under tension to draw the cover down on the bottle.

5. In a bottle closure the combination of a cover having elastic legs and a connected lever ring on the lcgs'adapted to engage the bottle head and place the legs under tension.

6. A bottle closure comprising a cover for the mouth, depending elastic legs thereon, and an inclined conical lever ring on said legs adapted to engage the bottle head and disposed so as to draw down the cover as its inclination is'forci'bly altered, substantially as describedf 7. The combination with a bottle head having an anchorage ledge, of a cover with attached elastic arms, and a flared expansible ring attached to the arms, said ring e'ngaging the ledge and adapted when its outer edge is compressed to act as a lever to pull down the arms and cover on the bottle.

8. In a bottle closure the combination with a bottle head having an anchorage ledge, of a cover with resilient'meansto hold it down and a conical ring engaging the ledge and connected to the holding means and adapted to place the latter under stress as the ring is fulcrumed and turned against the ledge,

9. A bottle closure comprising a cover and an attached expansible ring of general conical form adapted to enga e the bottle as the fulcrum of a lever and raw down the attached cover When the ring is distorted.

10. In a bottle closure, in combination with a bottle head having an anchorage ledge, a closing cap comprising a cover for the mouth,

holding arms, and a lever member connected to said arms, adapted to draw the cover down on the bottle by changing the angularity of the said lever member.

11. A bottle closure com rising a coverin disk and an attached inc ined flange, sai flange being separated from the coverat intervals and the separated port-ions being inwardly and downwardly arched in order to engage the bottle head and induce a lever action when the inclination of said arches is forcibly altered, whereby to induce a pressure downward upon the said cover.

In testimony whereof I have hereunder signed my name, in the presence of the two subscribed witnesses.
